Chapter 2 Cells.
Protective outer covering of all cells that regulates the interaction between the cell and the environment.
Smallest unit of an organism that can carry on life functions.
States that all organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from other cells.
Rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria.
Green, chloroplast-containing, plant-cell organelle that uses light energy to produce sugar from carbon dioxide and water.
Constantly moving gel-like mixture inside the cell membrane that contains heredity material and is the location of most of the cell's life processes.
Cytoplasmic organelle that moves the materials around in a cell and is made up of a complex series of folded membranes; can be rough (with attached ribosomes) or smooth (without attached ribosomes).
Organelles that package cellular materials that transfer within the cell of out of the cell.
Living in a cell which a virus can actively multiplay or in which a virus can hide until activated by environmental stimuli.
Cell organelle that breaks down food and releases energy.
Organelle that controls all the activities of a cell and contains hereditary material made of proteins and DNA.
Structure, such as the heart, made up of different types of tissue that all work together.
Structure in the cytoplasm of a eukaryotic cell that can act as a storage site, process energy, move materials or manufacture substances.
Small cytoplasmic structure in which cells make their own protein.
Group of similar cells that work together to do one job.
A strand of hereditary material surrounded by a protein coating.
